n is the primary object nf my invention tn provide a dam ner in a motor vehicle to subdue or eliminate body vibrations caused by torque re-action and` other motor vibra-A tions or impulses.

Another object of my invention is'to interpose friction between the internal combustion engine and an automobile'body to damlpen periodic vibrations of the body caused y synchronization of the body and other parts with the engine impulses.

With the a ve and other objects in view, my invention consists in the arrangement,

combiuiation and construction of the various parts of my improved device, as described in Y the specification, claimed in myclaims and shown in which:

Fig. 1 is a front view, shown artly 1n ele'- the accompanying drawings, yin

I vation and partly in section, o an mternal combustion engine with my im roved device attached thereto positioned in ront of a portion ofthe body dash, shown in elevation.

Fig. 2 is a side elevation of my improved device attached to the head of the internal combustion engine and bearingagainst a .portion of a body dash shown in section.

I have shown a conventional internal combastion engine mounted by arms 11 in rubber blocks 12, such for instance, as those shown in Patent No. 1,57 8,673, issued March 30th, 1926. The engine` 10 is provided w1th a cylinder head 13 secured by studs 14 and nuts 15 'to a cylinder block 16. Bosses 17 are cast on the top of the head 13 through whlch the studs 14 pass.

Positioned on and secured to the bosses 17 at the rear of the head 13 by the studs 14 and nuts 15 is my-improved device, in the construction of which I provide an angle plate 19 having a vertical side 420 extendmg up from the head 13 and parallel with a conventional dash 21 of an automobile body, not shown.

A plate 22 having a friction linin 23 bearing against the dash 21 is positione by bolts 24 threaded through the side 20 of the angle plate 19. The ends v25 of the bolts 'M are placed in seats 26 cut into the plate 22. Lock nuts 27 that bear against the side 20 of the explosions. This vibratory movement will Igle plate 19 prevent the bolts 24 from ac# be conveyed through the angle plate 19 and bolts, 24 to plate 22 and lining 23. The lining 23 being held ag'amst' the dash 21 b the bolts 24 tends to move back and forth. yThus the friction of the lining 23 against the dash 21 nwill prevent theim ulses of the engine from being transferre as synchronous vibration to `the The pressure of the lining against the ash 21 may be varied by adjustin the nuts 27, the side 20 of the angle plate 19 icing held under tension.

It will be noted that the angle shape of the slate 19 admirably adapts the device to ampen both vertical and sidewise vibrations, because the width of the side' 2O is suiiicient to lend rigidity thereto in sidewise direction, and the height of the piece 20 is suicient to lend rigidity thereto vertically. Vibrations occurring in a combination of the two direc-l tions are therefore admirably cared for.

It will be obvious that various changes may be made in the arrangement, combinations and construction ofthe various parts of my improved device, without de arting from the spirit of my invention an itis my intension to cover by my claims such changes asy be reasonably included within the scope thereof.l

1. In a motor vehicle, the combination of an automobile body having a. dash, an engine, an angle plate having one side thereof secured to the top of said engine and the other side extending upward and parallel tosaid dash, a plate, a friction lining attached to said plate and means projecting from said angle said dash.

2. In a motor vehicle, the combination of an automobile body having a dash, an engine mounted on cushioning means, an angle plate plateadapted to press said lining against having one side thereof secured to the top of l said engine and the other side extending u pward and parallel to said dash, a plate, fricioo tion lining secured to said plate, bolts through said angle plate and adapted to osition and reas said lining 'nst said das and means or normally holding said bolts against turnmg. In a motor vehicle2 the combination of an automobile body having a dash, an en e mounted in rubber blocks, an angle plate aving one side thereof secured to t e top of said 5 motor and the other side extending up parallel to said dash, a late havin a seat cut therein, a friction ining attac ed to said plate, bolts threaded through said angle plate aving their ends positioned in the seat in said plate to press the linin against said dash and nuts on said bolts adapted to keep the same from normally rotati and to hold said plate under a spring tension.
